I got very lucky here. I had an assistant who was holding my nikon SB 28 at about 1/2 power for formals, I had just shot a few images of the car and walked away from needing my flash for about 20 minutes or so. As they were leaving in their car, I decided I would pan with the car to make a movement shot and at the very last second, I gestured to my assistant to run (I'm sorta running to) and pointed for her to stand there...
I snapped one frame that pretty much…
